Problems encountered when inquiring about ball valves
Thread Content
Inquiry regarding ball valves: The seat is described as “RPTFE With secondary metal to metal”. What does this mean? Does it refer to a ball valve with a PTFE lining? What do RT-10%, RT-50%, and RT100% mean? What does “Rt-10% Extended Bonnet as per BS6364(Non Cold Application)” mean?
RT is a type of non-destructive testing; radiographic inspection is abbreviated as RT. There are mainly four types of non-destructive testing: radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT), and liquid penetrant testing (PT). The percentage later on should be the proportion of product samples inspected, right?
RPTFE is reinforced polytetrafluoroethylene; the following sentence refers to the performance standards for cryogenic valves
RPTFE is a reinforced polytetrafluoroethylene, and it is a commonly used material for ball valve seats
